The Dufek massif is a rugged, mostly snow-covered massif about 43 km in length in Queen Elizabeth Land in West Antarctica . It looms in the Forrestal Range in the northern section of the Pensacola Mountains .

The massif was discovered and photographed during the transcontinental flight of the United States Navy on January 13, 1956 as part of the first Operation Deep Freeze from McMurdo Sound to the Weddell Sea and back. The Advisory Committee on Antarctic Names named it in 1957 after Rear Admiral George J. Dufek (1903-1977), commander of Task Force 43 during this operation. The mapping was done by the United States Geological Survey from 1967 to 1968 and using aerial photographs by the United States Navy from 1964.
